I am not an expert in mineralogy by any means, so I will defer to someone else that may be better trained.
The "quartz" part is easy, and I assume you know what that is. The "positive" part refers to inclusions of another crystaline structure within the material. This enclosed crystal structure can be positive or negative. Positive inclusions are made of the same material as the surrounding material. Negative inclusions are made of some other material.
So, "positive quartz" refers to a piece of quartz crystal that has a piece of a different quartz crystal inside of it. Visually, you see the included crystal as a sort of "ghosted outline".
I am dealving into personal conclusion for this next part... since rutile has a crystaline structure, the well known "rutilated quartz" would be a good example of negative quartz. I can't say if a non-crystaline inclusion (for example, a bit of organic material or water trapped in a rapidly formed crystal) is considered to be a negative crystal or not.
There is probably a local mineralogy society in your area. Such groups are made of of mineralogy enthusiasts at every level of knowledge. You might want to seek someone in one of these local groups if you don't get a better answer here. Based on my experience these guys are more than happy to spread their expert knowledge around to anyone who is interested enough to learn or even ask the question.
